Quizplus · Accepted Answer

Lymph nodes primarily function to remove pathogens from lymph, which is the fluid that circulates through the lymphatic vessels. The nodes contain immune cells that can identify and attack harmful microorganisms, helping to prevent infection and disease. Lymph nodes do not remove pathogens from the blood, separate lymphatic fluid from plasma, or destroy old red blood cells.
